WebM Enters the Firefox Trunk

Less than a month after the announcement that the WebM codec would go open source, Mozilla has already incorporated support into the Firefox trunk. This ensures that WebM videos will be playable natively when the HTML5 video tag is present.

Mozilla developer Chris Pearce credits Chris Double, Matthew Gregan and himself for integrating support into the Firefox trunk.

Windows programmers can build WebM into Firefox without extra changes to the build configuration, assuming they aren't building on Win32. In that case, MASM is necessary to compile the libvpx optimized assembly. Win64 is not supported at this time.
